Abstract
A feed worm located at the bottom of an infeeding hopper is shaped in the form of at least one convolution or turn, without a central core or shaft. The sharp edge or knife edge of the feed worm lying forwardmost in the direction of rotation attacks a block of frozen meat at a location higher than by using previously known feed worms having a central shaft and core. The central shaft or core prevents the frozen block from moving in the downward direction as far as is possible with a feed worm devoid of a core or central shaft. The feed worm includes a thick-walled tube of steel in which over one-half of the tube has been cut away along helical surfaces forming sharp edges with the outside surface of the tube.
